Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an IC contact unit, an IC card processing unit,

The present invention relates to an IC contact point unit, an IC card processing apparatus, and an automated transaction apparatus, and more particularly to an IC contact point unit, an IC card processing apparatus, and an automated transaction apparatus which use a transfer force of an IC card to push an IC contact- A contact point unit, an IC card processing apparatus, and an automated transaction apparatus.

Generally, an automatic transaction apparatus such as an automatic teller machine is provided with an IC card processing apparatus having an IC contact unit therein. The IC card processing apparatus carries the IC card to a position where it can read and write, and reads and writes variable data such as transaction data recorded on the IC card by the IC contact point unit. It is necessary to bring the terminal on the IC card side and the terminal on the IC contact point unit side into contact with each other when the variable data is read and written. The configuration of the contact portion is disclosed in, for example, Patent Document 1 below.

Patent Document 1 discloses an IC contact unit in which a terminal on the side of an IC contact unit is pressed and brought into contact with a terminal on the IC card side by using a conveying force of the IC card. Specifically, the IC contact point unit includes a movable block having an IC contact and a claw member, a guide portion for guiding the movable block, and a holding portion for holding the claw member of the movable block in a standby position retracted from the conveying surface of the IC card, When the claw member moved by the actuator to the protruding position receives the conveying force of the IC card and moves the claw member along with the movement of the claw member, Direction of the IC contact unit is guided in the horizontal direction with respect to the direction of the IC contact unit.

According to this Patent Document 1, since the IC card side terminal and the IC contact point side terminal are brought into contact with each other by using the conveying force of the IC card, the actuator moves the claw member of the movable stand to the protruding position It is possible to reduce the overall size of the apparatus and to reduce the power consumption.

Japanese Patent No. 3683489

However, in the structure described in Patent Document 1, when the claw member moves to the projecting position receiving the conveying force of the IC card, the distance between the IC contact provided by the movable table and the conveying surface of the IC card becomes very small. At this time, if there is an abnormal portion such as warpage, distortion, or crack in the IC card to be conveyed, there is a problem that the abnormal portion interferes with the IC contact point and destroys the IC contact point.

Further, since a small actuator is employed, it is necessary to precisely adjust the mounting position of the actuator in order to secure a sufficient driving force, which requires a complicated operation. If the mounting position of the actuator is defective, the claw member of the movable stand can not be properly moved to the protruding position, and the IC card side terminal and the IC contact unit side terminal can not be brought into contact with each other by using the carrying force of the IC card.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and it is an object of the present invention to reduce the size and power consumption of the entire device and to prevent the IC contact from being broken, and to secure sufficient driving force of the actuator An IC contact unit, an IC card processing device,

In order to solve such a problem, in the present invention, the IC contact point unit includes a first contact terminal block, a second contact terminal block, an elastic member, and a terminal block down portion, And a second link portion. The second contact terminal block includes a contact pin, a claw portion, and a stagger member. The elastic member biases a tensile force on the second contact terminal through the stagger member, The compression spring transmits the rotation operation of the first arm to the second arm until the rotation of the second arm is stopped, and the compression spring transmits the rotation of the second arm to the second arm, And after the rotation operation is stopped, the rotation operation of the first arm is absorbed and contracted.

According to the present invention, it is possible to reduce the size and power consumption of the entire device and to prevent the IC contact from being broken, and sufficient driving force of the actuator can be ensured without precisely adjusting the mounting position of the actuator.

(1) Configuration of IC card processing device

Fig. 1 shows the entire configuration of an IC card processing apparatus 1 according to the present embodiment. When the IC card is inserted, the IC card processing apparatus 1 operates the IC contact unit 20 provided therein to read and write variable data such as transaction data recorded on the IC card.

The IC card processing apparatus 1 comprises a conveying roller 10 and an IC contact point unit 20. The pair of conveying rollers 10 are arranged so as to be vertically opposed to the card conveying line X and rotate so as to convey the IC card along the card conveying line X. Here, the conveying roller 10 is rotated so as to convey the IC card from right to left.

The IC contact point unit 20 is provided between two pairs of conveying rollers 10 disposed on the front and rear in the direction of the card conveyance line X and is arranged upward with respect to the card conveyance line X. [ The IC contact point unit 20 reads and writes the variable data recorded in the IC card conveyed along the card conveyance line X.

The IC contact unit 20 presses the terminal (contact pin) of the IC contact unit 20 side to the IC card side terminal by using the conveying force of the IC card. The detailed configuration of the IC contact point unit 20 will be described with reference to Figs. 2 to 6. Fig.

(2) Configuration of IC contact point unit 20

Fig. 2 shows the top surface configuration when the IC contact point unit 20 is viewed from the Y direction in Fig. The IC card is transported from the right side to the left side. Hereinafter, details of each cross sectional configuration of the A-A cross section, the B-B cross section, and the C-C cross section will be described with reference to Figs.

(3) Configuration of IC contact unit when waiting for IC card

Figs. 3A to 3C show the entire configuration of the IC contact point unit 20 in the IC card standby state. FIG. 3A shows a section A-A in FIG. 2, and FIG. 3B shows a section B-B in FIG. Figure 3c also shows a cross section C-C of Figure 2. The configuration of the IC contact unit 20 at the time of IC card standby will be described below with reference to Figs. 3A to 3C. Fig.

The IC contact point unit 20 includes an actuator 21, a plunger 22, a terminal block pressure lower portion 23, a first contact terminal block 24, a second contact terminal block 25, an elastic member 26, And the like.

The actuator 21 sucks the plunger 22 at a predetermined timing when the IC card is conveyed along the card conveyance line X. The predetermined timing is, for example, a timing at which the claw portion 253, which will be described later, makes it possible to hold the end portion of the IC card. The driving force of the actuator 21 (suction force for sucking the plunger 22) is maximized when the end portion of the plunger 22 abuts against the bottom portion.

The plunger 22 is connected to the actuator 21 so as to be suckable, and is connected to the terminal block pressure lower portion 23. When the plunger 22 is sucked by the actuator 21, the plunger 22 transfers the suction operation to the terminal block pressure lower portion 23.

When the suction operation from the plunger 22 is transmitted, the terminal block pressure lower portion 23 moves in the suction direction of the plunger 22 at one end, which is the connection point with the plunger 22. Accordingly, the terminal block pressure lower portion 23 rotates clockwise about a fixed shaft for fixing the terminal block pressure lower portion 23, and the other end presses the first contact terminal block 24 downward.

Here, the terminal block pressure lower portion 23 includes a first arm 23A, a compression spring 23B, a second arm 23C, a first rotary shaft 23D, and a second And includes a rotary shaft 23E. One end of the first arm 23A is rotatably connected to the plunger 22 and when the plunger 22 is sucked, the first arm 23A rotates clockwise about the first rotation axis 23D.

A compression spring 23B is connected to the other end of the first arm 23A and the compression spring 23B is connected to the first arm 23A to transmit the rotation operation of the first arm 23A to the second arm 23C And the second arm 23C. Accordingly, when the first arm 23A rotates clockwise, the second arm 23C also rotates clockwise about the first rotation axis 23D.

The second arm 23C presses down the end of the first contact terminal block 24 while rotating the pressing roller 231C when rotating together with the first arm 23A in the clockwise direction. It is possible to suppress the abrasion of the contact portion between the second arm 23C and the first contact terminal block 24 by pressing down the first contact terminal block 24 while rotating the pressing roller 231C.

When the second arm 23C is rotated to the position of the stopper 32 formed on the bracket 30, the stopper 32 stops the rotation of the second arm 23C. The second arm 23C stops rotating by the stopper 32 while the first arm 23A is rotated in the direction of the plunger 22 when the plunger 22 continues to be attracted further by the driving force of the actuator 21 Is not moved to the vicinity of the bottom of the actuator 21, it further rotates clockwise about the second rotation shaft 23E.

When the suction operation of the plunger 22 is stopped or the compression range of the compression spring 23B reaches the limit value, the first arm 23A is rotated in the clockwise direction about the second rotation axis 23E Lt; / RTI > The lower end 23 of the terminal block rotates the second arm 23C to the position of the stopper 32 in accordance with the suction operation of the plunger 22. When the suction operation of the plunger 22 continues further, The first arm 23A is slightly rotated to absorb the force by the first arm 23A.

Thereby, the actuator 21 can suck the plunger 22 to the vicinity of the bottom portion. By sucking the plunger 22 to the vicinity of the bottom portion, the driving force of the actuator 21 can be sufficiently secured.

The first contact terminal block 24 is brought into contact with the contact pin 251 by the first link portion L1, the second link portion L2 and the bracket 30 or the like before being pressed down by the terminal block pressure lower portion 23, Is held for a predetermined distance &thetas; 1. On the other hand, when the first contact terminal block 24 is pressed down by the terminal block pressure lower portion 23, the first contact terminal block 24 rotates counterclockwise with the first link portion L1 as a rotation axis.

An installation area of the second contact terminal block 25 is formed at the center of the first contact terminal block 24. The first link portion L1 is formed at one end and the second link portion L2 is formed at the other end. When the first contact terminal block 24 rotates counterclockwise about the first link portion L1 as a rotation axis, the first contact terminal block 24 transmits the rotation operation to the second contact terminal block 25 through the second link portion L2.

The second contact terminal block 25 has a contact pin 251 at a central portion for actually reading and writing variable data recorded in the IC card, and a claw portion 253 is formed at one end. The second contact terminal block 25 is connected to the first contact terminal block 24 via the second link portion L2. At the other end, a staple member 252 is formed. The staple member 252 is provided with an elastic member 26.

When the rotation of the second contact terminal block 25 from the first contact terminal block 24 is transmitted through the second link portion L2, the elastic member 26 is straddled on the interlocking member 252, And rotates in a counterclockwise direction together with the cam 24. At this time, the claw portion 253 moves downward relative to the card conveyance line X.

The elastic member 26 is provided so as to exert an urging force substantially parallel to the direction of the card conveyance line X and in a direction opposite to the conveying direction of the IC card when the IC card is in standby, (252) formed on the bracket (30) and the other staggering member (31) formed on the bracket (30). The elastic member 26 biases the force for pulling the second contact terminal block 25 in the right direction through the padding member 252. [ The elastic member 26 is, for example, a spring coil.

(4) Configuration of IC contact unit when IC card engagement is supported

Figs. 4A to 4C show the entire configuration of the IC contact unit 20 at the time of holding the IC card. Fig. 4A shows a cross section taken along the line A-A in Fig. 2, and Fig. 4B shows a cross section taken along line B-B in Fig. Fig. 4C also shows a cross section C-C in Fig. Hereinafter, the structure of the IC contact unit 20 at the time of holding the IC card will be described with reference to Figs. 4A to 4C. Fig.

When the IC card is conveyed along the card conveyance line X, the IC contact point unit 20 sucks the plunger 22 at the predetermined timing. As the plunger 22 is sucked, the terminal block pressure lower portion 23 rotates clockwise to press down the first contact terminal block 24. When the pressing roller 231C of the second arm 23C rotates to the position of the stopper 32, the second arm 23C stops rotating.

In this case, when the suction operation of the actuator 21 continues, that is, when the end of the plunger 22 does not reach the vicinity of the bottom of the actuator 21, the first arm 23A is rotated about the second rotation axis 23E And rotates clockwise.

When the first contact terminal block 24 rotates counterclockwise about the first link portion L1, the counterclockwise force of the second contact terminal block 25 is biased by the second link portion L2. The second contact terminal block 25 also rotates counterclockwise. As a result, the claw portion 253 moves downward of the card conveyance line X.

The first contact terminal block 24 maintains a substantially horizontal state with respect to the card conveying line X in a state in which the claw portion 253 moves downward of the card conveying line X. [ In other words, the first contact terminal block 24 at the time of holding the IC card is kept at 0 at the angle with respect to the card conveyance line X direction. In this state, when the IC card is conveyed along the card conveyance line X, the second contact terminal block 25 holds the end portion of the IC card by the claw portion 253.

As the first contact terminal block 24 rotates in the counterclockwise direction, the second contact terminal block 25 rotates counterclockwise in the same manner. However, the second contact terminal block 25 rotates in the counterclockwise direction, Otherwise, the elastic member 26 is rotated in a state in which it is pulled in the right direction through the staple member 252. The force in the rightward direction and the upward direction (rightward inclined upward direction) is imposed on the second contact terminal block 25 after rotation.

As a result, the second contact terminal block 25 at the time of holding the IC card is fixed while maintaining a predetermined angle with respect to the card conveyance line X direction. Therefore, the distance (retraction amount) between the contact pin 251 and the card conveying line X at the time of holding the IC card can be made to be spaced apart by a predetermined distance? 2.

By increasing the amount of retraction of the contact pin 251 from the card conveyance line X, even when there is an abnormal part such as warpage, distortion, or crack in the IC card, the abnormal part is interfered with the contact pin 251 It is possible to prevent the contact pin 251 from being broken.

(5) Configuration of IC contact unit in IC card reading

Figs. 5A to 5C show the entire configuration of the IC contact point unit 20 in IC card reading. Fig. 5A shows a cross section taken along the line A-A in Fig. 2, and Fig. 5B shows a cross section taken along line B-B in Fig. Figure 5c also shows a cross-section taken along the line C-C of Figure 2. Hereinafter, the configuration of the IC contact point unit 20 at the time of reading the IC card will be described with reference to Figs. 5A to 5C. Fig.

When the IC contact point unit 20 holds the IC card by the claw portion 253, the IC contact point unit 20 receives the conveying force of the IC card. As a result, the second contact terminal block 25 moves leftward. The first contact terminal block 24 also moves leftward through the second link portion L2.

When the second contact terminal block 25 receives the conveying force from the IC card, the second contact terminal block 25 moves leftward with the elastic member 26 being stretched over the stretching member 252. At this time, when the guide shaft 254 formed on the second contact terminal block 25 comes into contact with the guide roller 34 and then the second contact terminal block 25 further moves leftward, the guide shaft 254 And is guided in the left downward direction along the clockwise rotation of the guide roller 34. [

When the guide shaft 254 is guided in the left downward inclination direction along the guide roller 34, the second contact terminal block 25 resists the force in the rightward inclined upward direction, which is urged by the elastic member 26, The end on the side of the member 252 is press-fitted downward. As a result, the contact pin 251 is pressed against the IC card to make contact therewith. The contact pin 251 is brought into contact with the IC card at this time.

The IC contact point unit 20 is provided with a convex portion 241 and a guide groove 33 for restricting the movement of the first contact terminal block 24 in the left direction and the convex portion 241 and the guide groove 33 The first contact terminal block 24 moves leftward to a predetermined position and then stops. Since the second contact terminal block 25 is connected to the first contact terminal block 24 by the second link portion L2, the second contact terminal block 25 stops following the stop of the first contact terminal block 24. [

Thereafter, variable data recorded on the IC card is read and written through the contact pin 251. [

(6) Isometric configuration of IC contact unit

6 is an exploded perspective view of the IC contact point unit 20. Fig. Here, the illustrated members are described in order from the left.

The second contact terminal block 25 has a contact pin 251 at the center thereof. The contact pins 251 do not come into contact with the IC card when waiting for the IC card and when holding the IC card (Figs. 3 and 4), and contact the IC card only when reading the IC card (Fig.

At the end of the second contact terminal block 25, a straining member 252 is formed. The elastic member 26 is stretched over the straining member 252. This elastic member 26 always exerts a tensile force on the second contact terminal block 25. On both sides of the second contact terminal block 25, a guide shaft 254 is formed. The guide shaft 254 is guided by the guide roller 34 when the IC card is read, and presses the second contact terminal block 25 downward.

The first contact terminal block 24 has a mounting area of the second contact terminal block 25 at the center thereof. And the second contact terminal block 25 rotates in this mounting area (Figs. 3 to 5). The second link portion L2 and the first link portion L1 are formed at the end of the first contact terminal block 24. [ The second link portion L2 rotatably connects the second contact terminal block 25.

The first link portion L1 is engaged with the guide groove 33 (not shown here) of the bracket 30 and is engaged when the IC card is latched (Figs. 3 and 4) The terminal block 24 is rotatably connected to the bracket 30. 5), the first contact terminal block 24 is connected to the bracket 30 so that the first contact terminal block 24 moves along the guide groove 33. [

The terminal block pressure lower portion 23 is provided with a pressing roller 231C which is in contact with the first contact terminal block 24 so as to be pressed down and a second arm 23C provided with the pressing roller 231C, And a first arm 23A. The first arm 23A rotates about the first rotation shaft 23D as the plunger 22 sucks.

When the first arm 23A rotates, the rotational motion is transmitted to the second arm 23C through the compression spring 23B. The second arm 23C receives a pressing force from the compression spring 23B and rotates in the same direction as the first arm 23A about the first rotation axis 23D.

When the pushing roller 231C of the second arm 23C comes into contact with the stopper 32 (not shown here) and the suction operation of the plunger 22 continues even after the rotation operation is stopped, Is slightly rotated about the second rotation axis 23E. As the first arm 23A rotates slightly, the actuator 21 can suck up the plunger 22 to the maximum allowable range. Therefore, the driving force of the actuator 21 can be sufficiently exerted.

The first contact terminal block 24 is rotated by the terminal block pressure lower portion 23 pressing down the first contact terminal block 24 and the second contact terminal block 25 is also rotated in accordance with the rotation operation. The claw portion 253 can hold the conveyed IC card. The second contact terminal block 25 holds the IC card by the claw portion 253 and then receives the conveying force of the IC card to move to the card conveying line X. [ The second contact terminal block 25 moves to a predetermined position and then presses the contact pin 251 against the IC card to read and write variable data recorded in the IC card.

(7) Effect according to the present embodiment

As described above, according to the IC contact point unit 20 of the present embodiment, the actuator 21 may be a small one having a driving force enough to move the claw portions 253 downward of the card conveyance line X, The overall size can be reduced and the power consumption can be reduced. One end of the second contact terminal block 25 having the contact pin 251 is rotatably connected to the first contact terminal block 24 through the second link portion L2 and the other end is connected to the first contact terminal block 24 by the elastic member 26 The amount of retraction of the contact pins 251 at the time of standby of the IC card and at the time of retaining the engagement can be increased. Therefore, it is possible to avoid the breakage of the contact pin 251 while reducing the overall size of the apparatus and reducing power consumption. And the suction force of the plunger 22 is absorbed even after the first contact terminal block 24 is completely pressed down. Therefore, even if the mounting position is not precisely adjusted, The driving force can be sufficiently secured.
